HUMAN VIBRATION ANALYSERPROVIDES ALL DATA REQUIRED BY THE DIRECTIVEIN A HANDHELD FORMAT.Bruel & Kjaer introduces a portable system for acquisition,measurement and evaluation of human vibration.The Type 4447 Human Vibration Analyser is designed for monitoringexposure of human operators to the harmful influences of vibrationof hand-tools, machinery, heavy vehicles, etcetera.It is a compact, battery-driven, standalone instrument ideal for fieldwork and with a versatile graphics display for control of the instrumentand analysis of results. Four buttons control all functions, and allnecessary data is displayed for instant assessment of exposure tovibration. A USB interface provides for archiving and post processingof the data for calculation of vibration doses.Among the parameters which the Type 4447 simultaneously measuresand calculates are triaxial running RMS vibration and peak vibration,weighted or unweighted, crest factor for each axis, frequency-weightedhand-arm vibration and whole-body vibration, the combined vibrationon all three axes as a vector sum, MTVV (maximum transient vibrationvalue), MSDV (motion sickness dose value), and VDV (vibration dosevalue). The Type 4447 is delivered together with a software packagefor calculation of vibration exposure to check the action values and limitvalues as stated in European Directive 2002/44/EC.Bruel & Kjaer sought input from many interested parties in the designand development of the instrument. They include consultants workingwith measurements of, and risk evaluations caused by, exposure tooccupational vibration; occupational health departments; manufacturersof building machinery, freight vehicles and other machinery; manufacturersof anti-vibration pads, seats and personal protection equipment;manufacturers of all kinds of hand-tools; and educational and medicalinstitutions.About Brüel & KjærWith more than 60 years experience, Brüel & Kjær is a worldleading manufacturer and supplier of sound and vibrationsolutions for use in a wide range of applications includingenvironmental noise measurements, building acoustics,vibration measurements and quality control for use in theautomotive, aerospace and consumer industries, as wellas by local authorities. __________________________________________________For more information, please contact :-Bruel & Kjaer UK Ltd.Bedford House, Rutherford, Close, Stevenage, Herts.
